When the vehicle is in a static state or a reversing state, a scratch may occur due to unnoticed vehicles beside the vehicle, pedestrians, bicycles and the like, so that the loss of the vehicle is caused. Based on the foregoing technical problem, this embodiment provides a vehicle monitoring method, which determines whether there is a moving potential collision object moving to a vehicle by monitoring real-time distance information of the potential collision object around the vehicle, and when there is the moving potential collision object, sends a turn signal control instruction to a vehicle light electronic control unit by monitoring the real-time distance of the moving potential collision object and the preset safety distance in real time, so that the vehicle light electronic control unit controls to turn on and off a corresponding turn signal, thereby implementing early warning on surrounding pedestrians or vehicles, and avoiding vehicle loss caused by vehicle scratch and the like in a static state or a reverse state, specifically referring to fig. 1, where fig. 1 is a flowchart of the vehicle monitoring method provided in this embodiment of the present application, and specifically includes:
s101, acquiring real-time distance information of all potential collision objects around the vehicle sent by the distance measuring equipment.
The embodiment does not limit the distance measuring equipment and the number of the distance measuring equipment, and a user can customize the setting. The distance measuring device may be an ultrasonic sensor, a camera distance measuring device. When the distance measuring equipment is an ultrasonic sensor, the distance of pedestrians or potential collision objects around the vehicle is monitored by using the ultrasonic sensor, mainly by using the ultrasonic principle, ultrasonic waves are generated by a probe arranged on the vehicle, the vertical distance between the vehicle body and the object of the vehicle is calculated by the ultrasonic waves encountering the signals reflected by the object, and the distance data can be transmitted to a vehicle-mounted diagnosis system in a wired or wireless way, wherein the vehicle-mounted diagnosis system can be an OBD device, the number of the ultrasonic sensors can be 2, 3, 4, 5 and the like, the installation position of the ultrasonic sensor on the vehicle is not limited in the embodiment, a user can install the distance measuring equipment in a customized way as long as the real-time distance information of the potential collision objects around the vehicle can be obtained, for example, when the number of the ultrasonic sensors is 4, the distance measuring equipment can be installed on four sides of the vehicle, at this moment, each ultrasonic sensor monitors real-time distance information of a potential collision object corresponding to the side face and the vehicle, certainly, when the vehicle is seen as a rectangle, four ultrasonic sensors can be installed at four right angles, an ultrasonic sensor a, an ultrasonic sensor b, an ultrasonic sensor c and an ultrasonic sensor d can be arranged in sequence, at this moment, the four side faces can be monitored by using two ultrasonic sensors, the ultrasonic sensor a and the ultrasonic sensor b monitor the first side face, the ultrasonic sensor b and the ultrasonic sensor c monitor the second side face, the ultrasonic sensor c and the ultrasonic sensor d monitor the third side face, and the ultrasonic sensor d and the ultrasonic sensor a monitor the fourth side face. When the range unit is the range unit of making a video recording, not restricting the model and the quantity of the range unit of making a video recording, the user can self-define the setting, can refer to ultrasonic sensor to the mounted position of the range unit of making a video recording on the vehicle, and this embodiment is no longer repeated. It will be appreciated that the above-described,
the distance measuring device calculates the actual distance between the vehicle and all the surrounding potential collision objects, namely real-time distance information, records the distance data between the vehicle and other surrounding potential collision objects, and then sends the distance data to the vehicle-mounted diagnosis system, so that the vehicle-mounted diagnosis system executes the steps S102-S104.
S102, judging whether a moving potential collision object moving towards the vehicle exists in all the surrounding potential collision objects according to all the real-time distance information.
And judging the real-time distance information of the potential collision objects in all directions according to an algorithm, and if the potential collision objects move towards the direction of the vehicle at present, finding that the distance from the vehicle is closer and closer through the distance record, and indicating that the vehicle moves towards the direction of the vehicle. The determination method is not limited in this embodiment, and may be that when there is a potential collision object, the distance from the vehicle at the first time is m, and after a certain time interval, the distance from the vehicle at the second time is n, and m > n, at this time, it is verified that the potential collision object moves toward the vehicle, and the potential collision object is determined as a moving potential collision object; of course, it is also possible that when there is a potential collision at the third time at a distance p from the vehicle, at a later time at a distance q from the vehicle at the fourth time, and the difference distance obtained by p-q is greater than the distance threshold, the potential collision is proved to be moving toward the vehicle, and the potential collision is determined to be a moving potential collision.
S103, if the mobile potential collision object exists, comparing the real-time distance of the mobile potential collision object with a preset safety distance to obtain a comparison result, wherein the real-time distance is data in the real-time distance information.
Of course, if the number of the moved potential collision objects is 5, the corresponding real-time distances are 5, and at this time, the real-time distances are sequentially compared with the preset safety distance to obtain a comparison result.
The present embodiment does not limit the preset safe distance, which may be 5m, 3m, or 2m, as long as the purpose of the present embodiment can be achieved.

The comparison mode can also compare a difference value obtained by subtracting the real-time distance from the real-time preset safety distance, and compare the difference value with the target difference value to obtain a comparison result, wherein the comparison result comprises that the difference value is larger than the target difference value, the difference value is smaller than the target difference value, and the difference value is equal to the target difference value.
And S104, obtaining a steering lamp control instruction according to the comparison result, and sending the steering lamp control instruction to the vehicle lamp electronic control unit so that the vehicle lamp electronic control unit can execute corresponding operation.
In an achievable real-time mode, when the comparison result shows that the real-time distance information is greater than the preset safe distance, the corresponding steering lamp is in an off state, and therefore the steering lamp control instruction is an instruction of the corresponding steering lamp in the off state and is sent to a vehicle lamp electronic control unit (vehicle lamp ECU), so that the vehicle lamp ECU realizes the off of the corresponding vehicle lamp; when the comparison result shows that the real-time distance information is smaller than the preset safe distance, the corresponding steering lamp is in an on state, so that the steering lamp control instruction is an instruction of the corresponding steering lamp on state and is sent to a vehicle lamp electronic control unit (namely, a vehicle lamp ECU), and the vehicle lamp ECU can realize the on of the corresponding vehicle lamp; and when the comparison result shows that the real-time distance information is equal to the preset safe distance, the corresponding steering lamp can be in an on state or an off state.
In another practical implementation manner, when the comparison result is that the difference is smaller than the target difference, the corresponding turn signal lamp is in an off state, and therefore the turn signal lamp control instruction is an instruction of the corresponding turn signal lamp off state and is sent to a lamp electronic control unit, namely, a lamp ECU, so that the lamp ECU realizes the turning-off of the corresponding lamp; when the difference is larger than the target difference, the corresponding steering lamp is in an on state, so that the steering lamp control instruction is an instruction of the corresponding steering lamp on state and is sent to a vehicle lamp electronic control unit (namely a vehicle lamp ECU), so that the vehicle lamp ECU realizes the on of the corresponding vehicle lamp; when the comparison result is that the difference is equal to the target difference, the corresponding turn signal lamp may be in an on state or an off state.
Based on the technical scheme, the embodiment judges whether the movable potential collision object moving towards the vehicle exists by monitoring the real-time distance information of the potential collision object around the vehicle, and when the movable potential collision object exists, the real-time distance and the preset safety distance of the movable potential collision object are monitored in real time, and a steering lamp control command is sent to the vehicle lamp electronic control unit, so that the vehicle lamp electronic control unit controls the turn-on and turn-off of the corresponding steering lamp, the early warning of surrounding pedestrians or vehicles is realized, and the vehicle loss caused by scratch of the vehicle and the like in a static state or a reversing state is avoided.

and after detecting that the vehicle OBD interface is accessed, sending a VIN code reading instruction to the vehicle OBD module so that the vehicle OBD module can obtain VIN code information according to the VIN code reading instruction.
The OBD device is provided with an LINUX or ANDROID operating system, so that a lower computer program can be operated in the OBD device, and communication can be carried out through a hardware driving program and the ranging device to acquire real-time data. In addition, the hardware of the OBD device comprises hardware transceivers of common vehicle protocols such as KWP, CAN, PWM, VPW and the like, and the hardware transceivers CAN communicate with each Electronic Control Unit (ECU) of the vehicle through an OBD interface of the vehicle. The OBD device is inserted into an OBD interface of a vehicle and is powered by the OBD, the No. 16 pin is a power line, the No. 4 pin is a ground wire, and the No. 5 pin is a signal ground wire.
The method comprises the steps that after an OBD device is powered on, a lower computer program automatically runs, VIN code reading commands are sent to a vehicle OBD module firstly, since a protocol of a vehicle cannot be confirmed at first, the VIN code reading commands of each protocol are sent once in sequence until the vehicle OBD module returns VIN information, the common protocols comprise CAN, KWP, ISO9141, PWM and VPW, communication parameters and commands of each protocol are different, and the VIN code reading commands are written in the lower computer program, for example, communication pins of the CAN protocol are 6 and 14, the baud rate is 500K, and the VIN code reading commands are 0x0807df 0209020000000000.
And reading VIN code information fed back by the OBD module of the vehicle.
And the vehicle OBD module returns the VIN code information through a reply command.
And determining the vehicle type corresponding to the vehicle according to the VIN code information.
The VIN code information includes a VIN code, and a specific vehicle type of the vehicle can be analyzed from the 17-byte VIN code, for example, if the VIN code is WDD2210222a253260, it indicates that the vehicle series is a courtesy (BENZ), and the vehicle type is S350.
And obtaining the diagnosis function information of the vehicle lamp electronic control unit corresponding to the vehicle type from the diagnosis protocol file.
And then, according to the analyzed specific vehicle type, the diagnostic protocol file in the OBD device is used for searching the diagnostic function information of the vehicle lamp control system corresponding to the vehicle type. The diagnostic function information mainly comprises a communication pin, a protocol type, a communication baud rate, a system filtering ID, a vehicle lamp opening and closing command and the like of the system.
And establishing a communication link with the electronic control unit of the vehicle lamp by utilizing the OBD bus according to the diagnostic function information.
Firstly, an OBD device establishes a communication link with a vehicle lamp electronic control unit of a vehicle lamp control system through an OBD bus, communication parameters of a transceiver of the OBD device need to be set when connection is established, for example, a protocol type is set to be a CAN type, communication pins are No. 6 and No. 14 pins, a communication baud rate is 500K, a filtering ID of the system is that a sending ID is 0Xde20, and a receiving ID is 0xDE 40.
And sending a system activation command to the electronic control unit of the vehicle lamp.
After a communication link is established through the OBD bus, a system activation command, such as 0x1001, is sent to a vehicle lamp control system ECU, i.e., a vehicle lamp electronic control unit.
And receiving successful activation information fed back by the electronic control unit of the vehicle lamp.
The vehicle lamp control system ECU returns 0x5001 to indicate that the system is successfully activated.
And acquiring real-time distance information of the vehicle and all potential collision objects around, which is sent by the distance measuring equipment.
The OBD device can record distance data between the current vehicle and other surrounding objects according to information transmitted by the ultrasonic sensors in real time, namely, real-time distance information between the vehicle and all potential collision objects around, which is sent by the distance measuring equipment, is obtained.
And judging whether the moving potential collision objects moving to the vehicle exist in all the surrounding potential collision objects according to all the real-time distance information.

If the comparison result is that the mobile potential collision object is moving towards the vehicle and the distance between the mobile potential collision object and the vehicle is less than the preset safety distance, it needs to determine which lamps of the vehicle are to be turned on for warning according to the direction that the mobile potential collision object moves towards the vehicle, for example, if an object moves from the left side of the vehicle, a front and rear turn light on the left side of the vehicle needs to be turned on for warning.
The OBD device sends a command to turn on the left front and rear turn signal lamps to the vehicle lamp control system ECU, for example, the command to turn on the left front turn signal lamp is 0x2f090801, and the command to turn on the left rear turn signal lamp is 0x2f0a0801.
After receiving the command, the ECU of the vehicle lamp control system can turn on and flash the left front steering lamp and the left rear steering lamp of the vehicle to warn.
The OBD device determines the distance data transmitted from each ultrasonic sensor in real time.
If no object is found to be moving within the safe distance, which indicates that there is no danger at present, a command is sent to the vehicle lamp control system ECU to turn off the corresponding turn signals, such as the front left turn signal and the rear left turn signal which have been turned on before, and it is now necessary to turn off the two turn signals, such as a command 0x2f090800 to turn off the front left turn signal and a command 0x2f0a0800 to turn off the rear left turn signal. And the vehicle lamp control system ECU turns off the corresponding steering lamp and stops flashing after receiving the command. The whole distance monitoring and judging is carried out in real time, and corresponding operation is executed according to the judging result.
In one achievable real-time approach, further comprising: the stop operation is read to stop the alert operation. The reading may be by detecting that the STOP button is pressed or that the OBD device is unplugged from the OBD interface and no longer monitored and operated. By the mode, the operation is convenient, and the actual requirements of users are met.
